The phase shifted carrier PWM (PSC-PWM) method was used with capacitor voltage balancing algorithm as an inner control and the phase angle control algorithm was used as an outer control for MMC-DSTATCOM. The performance of MMC-DSTATCOM is investigated in MATLAB/Simulink for various simulations such as reactive power compensation, unbalanced and faulty grid conditions. © 2020 IEEE.en10.1109/SIELA49118.2020.9167091info:eu-repo/semantics/closedAccessDSTATCOMMicrogridModular multilevel converterPSC-PWMUnbalanced voltagesConference Object2-s2.0-85091331998
